The good thing is we can see Mou talking more on TV and dropping facts.
So Roma's decision was so fast, maybe behind it all was not happy Mourinho was still at Roma so he immediately got rid of him.
When De Rossi is unable to bring Roma in the Europa League, I'm sure Mou will rant in many media.
I think there is no need to wait until the end of the season to prove De Rossi's failure with AS Roma because yes, at this moment many people doubt De Rossi's quality because De Rossi does not have good experience. Moreover, AS Roma's situation at this moment is not completely good and therefore, it will be very difficult for De Rossi to recover AS Roma. It seems, AS Roma has big dreams by firing Mourinho and replacing Mourinho with De Rossi and maybe, AS Roma is hoping for a miracle. But unfortunately, these high hopes will not come true at all because yes, it looks like AS Roma will be a team that will be completely doubted for the rest of this season in all competitions.
You never know with these type of coaches,they have done not so well in the past with Roma but sometimes when they get to play in an European competition it looks like they magically transform into some other coach and they start winning games,even maybe repeat another miracle,to win an European cup again after that against Feyenoord.I think De Rossi has matured a lot since the time he failed at Roma and as they say experience can beat any degree so I want to be optimistic and think that he maybe do well in this second adventure with Roma.We have to see how he will do in Europe as most probably this will be his aim rather than saving Roma from the situation they are there in the Serie A.
